Dips in the sub-TeV gamma-ray light curves from central parts of galaxies due to transiting luminous stars
W. Bednarek, J. Sitarek, M. Ulatowski
The GeV-TeV γ-ray emission is observed from the direction of the source Sgr A^*, which is identified with the SMBH in the centre of our Galaxy. According to some models this γ-ray…
Inefficient acceleration of electrons in the shocked wind of the massive star Ori C within the Trapezium cluster
W. Bednarek
Shocked winds of massive stars in young stellar clusters have been proposed as possible sites in which relativistic particles are accelerated. Electrons, accelerated in such an env…
Orphan γ-ray flares from relativistic blobs encountering luminous stars
P. Banasiński, W. Bednarek, J. Sitarek
We propose that γ -rays in blazars can be produced during encounters of relativistic blobs of plasma with radiation field produced by luminous stars within (or close to) the jet. T…
High energy signatures of quasi-spherical accretion onto rotating, magnetized neutron star in the ejector-accretor intermediate state
W. Bednarek, P. Banasinski
We consider a simple scenario for the accretion of matter onto a neutron star in order to understand processes in the inner pulsar magnetosphere during the transition stage between…
Gamma-rays and neutrinos from dense environment of massive binary systems in open clusters
W. Bednarek, J. Pabich, T. Sobczak
TeV gamma-ray emission has been recently observed from direction of a few open clusters containing massive stars. We consider the high energy processes occurring within massive bin…
The optically thick homogenous SSC model: Application to radio galaxy NGC 1275
P. Banasinski, W. Bednarek
We consider the Synchrotron Self-Compton (SSC) model for jets in active galaxies in which produced -ray photons can be absorbed in collisions with the synchrotron radiation alre…
Expected gamma-ray emission from x-ray binaries
W. Bednarek
It is at present well known that conditions at some massive binary systems allow acceleration of particles and production of the GeV-TeV gamma-rays. However, which particles are re…
Gamma-rays from anisotropic IC e^{\pm} pair cascades in microquasars: Application to Cyg X-3
Julian Sitarek, Włodzimierz Bednarek
Microquasars have been expected to emit high energy gamma-rays due to their general similarities to the gamma-ray emitting blazars (evidences of relativistic jets, non-thermal radi…
A model for the two component gamma-ray spectra observed from the gamma-ray binaries
W. Bednarek
Observations of two well known binary systems (LS 5039 and LS I +61 303) with the satellite and Cherenkov telescopes revealed the broad band -ray spectra which seems to show two…
Gamma-rays from millisecond pulsars in Globular Clusters
W. Bednarek
Globular clusters (GCs) with their ages of the order of several billion years contain many final products of evolution of stars such as: neutron stars, white dwarfs and probably al…
